Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC Description
When the Enable Conditions are satisfied, the ECM checks that high and low outputs (Voltage level) are observed when OCVs are commanded. When a OCV output failure is detected, the appropriate fail counter is incremented.
If the failure threshold is exceeded 5 seconds during one diagnostic test (10 second), the test is failed and DTC is stored.
The MIL (Malfunction Indicator Lamp) will illuminate when the fault remains for 2 consecutive drive cycles.
